ABSTRACT:
A resin composition of wholly-aromatic thermotropic liquid crystal polyester resin containing 5 to 60% by weight of an inorganic filler selected from carbonates of alkaline earth metals, which is characterized in that the moisture content of the component materials to be fed to the melting step in preparation process of said composition is 0.1% by weight or lower. The resin composition and its formed articles are quite excellent in external appearance, thermal resistance, workability in plastics forming and especially in plating strength suitable for applying metal plating thereon.
